ran fine when purchased. has been driven every once in a blue moon for 20 years, to keep engine free. on non op. i drove it and after pouring in lucas additive in the tank it just stalled. must have loosened dirt in fuel system, so I took tank out and cleaned it. full of rust as they usually are of course. then put fresh gas (91 octane) and new filter, and some seafoam. it started a little bit so to speak but didn't quite run. I changed plugs and wires. no difference. I changed coil. no difference. cap and rotor looked good and were unavailable at parts store. points didn't look burned.
I hooked up fuel pumps directly to see if fuel came out the return and it sure does. but I don't know if they come on when cranking engine.

is there a relay somewhere?? hidden?? does it have the bosch k-jetronic and if so, where? does it have an ignition module somewhere? what else can it be, I'm about to get new ballast resistor that sits before the coil. I'm kinda stuck without my volt meter..

I'm used to diesels, they don't break so often like gas cars. (no electrical crap everywhere to make them run) in fact, if after 3 days of working on this thing I can't get it running today I will install 603 turbo into it. a real engine, so to speak...

all help appreciated!

A 603 will fit. There are a couple of threads about doing it to an R107. Of course, isn't a later diesel full of those electrical do-dads too?

The relay you're looking for is behind the kick panel by the passenger's right foot. There are several ice cube relays. One of them is for the fuel pump.

For these old D-jet motors, you're going to want to plumb a fuel pressure gauge that can accurately read 0-40psi in place of the cold start valve. You are shooting for 32psi the moment you turn it the key and it should stay there a while after you turn the car off. There are plenty of diagnostic threads in the veterans section with similar advice.

Good luck.

great. Yet I'm rather bad at finding threads on this forum... I bypassed the relay with a long wire, hooked it up directly and then tried starting the car. no response. Then I went and bought the cap, at a place 30 miles out. they gave me the wrong rotor but hey, at least I replaced the cap with a fresh one. still nothing. It's rather odd the way this car died. running fine, a little uneven idle but strong power on the freeway. then I pulled off cause it sounded like the center driveshaft support was clunking away and there was a parts store. poured the lucas fuel additive and a mile and a half later it died half. as in running very rough on maybe 4 cylinders.
then after all the work to clean tank, filter, new fuel, plugs and wires it just won't run at all. not even a little bit. not when you pour some fuel into the intake directly with filter off...

it has spark and gets fuel. the only thing I can think of is a huge blockage in the main line that the injectors come of off??


awesome that the 603 fits. I have a nice one laying around. with trans. runs fine without computer. (mike at Metric Motors builds them for marine purposes, no computer)

does it need replacing of motormounts and altering driveshaft?
